This radar level-measurement device is for bypass operations
The Optiwave 1010 FMCW radar level device is a two-wire, loop-powered HART transmitter designed for continuous level measurement of liquids in bypass applications in a variety of industries, including chemical, power, water and wastewater. When combined with the company’s BM 26 Advanced bypass chambers and magnetic level indicators, this device adds a 4–20-mA output to the mechanical devices. A combination can be ordered as a single package (called the BM 26 W1010), says the company. This device can also be welded onto any bypass chamber with internal diameter of 1.5–2 in. (38–56 mm). It has a measurement accuracy of±0.2 in. (5 mm), and it offers better accuracy in bypass applications, says its maker, because while reed chain and magnetostrictive level detectors measure the float position (which depends on product density), radar measures the liquid surface directly. — Krohne Messtechnik GmbH, Duisburg, Germany
